Plivo was founded after its founders, Venky Balasubramanian and Michael Ricordeau, found each other on Github and collectively decided, "[t]elephony is complex." Today, Plivo's focus is simple in statement, but complex in execution: Plivo offers "simple and powerful APIs that make it easier for businesses to develop telephony applications." Plivo's building block APIs allow developers to create telephony applications without learning the nuts and bolts of legacy telephony.

Our API directory now includes 373 telephony APIs. The newest is the ClickMeeting API. The most popular, in terms of mashups, is the Twilio API. We list 343 Twilio mashups. Below you'll find some more stats from the directory, including the entire list of telephony APIs.
